摘要
研究潜孔锤内部动力过程，优化潜孔锤性能，研制系列适应于不同工况条件及领域的特殊性能潜孔锤，以满足各种钻孔工程需求。将多种先进钻孔工艺方法融于潜孔锤钻进中，形成多工艺潜孔锤钻进工艺方法，以满足不同施工领域的钻孔施工需求，解决系列钻孔施工难题。
To meet the demand of varions drilling engineering, we have studied the internal dynamic process of DTH hammer to reveal the factors and principles aflecting DTH hammer’s performance, and develop a series of DTH hammer which can be applied to different working conditions and fields. We developed a multitechnology drilling technology of DTH hammer by merging several advanced drilling technology into one to meet the demand of drilling in different construction field, solve problems in drilling engineering and promote drilling technology.
